Interesting paper on "Degradation of Commercial Lithium-Ion Cells as a Function of Chemistry and Cycling Conditions" here: https://iopscience.iop.org/article/10.1149/1945-7111/abae37/pdf; Three degradation factors are explored: 1) Temperature, 2) DoD and 3) Discharge rate. (1/2)
I specifically care about LiFePo4 (LFP) chemistry, because our solar system's BYD battery is such. Strange to see that a 100% DoD doesn't appear to be harmful to this chemistry. Also surprised that a 0.5C discharge rate is worse for the battery than 1C or 2C..
